ABRAM D. WARD, OF CHICAGO, ILLINOIS.

' EXCAVATING-MACHINE.

To all whom it may concern:

Be it known that I, ABRAM D.NVAR a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented ful Improvements in Excavating-Machines, of which the following "is a. specification.

This invention relates to excavating machines; and its essentialobject is to pro vide a construction in which the excavating mechanism may be positioned and actuated as desired, irrespective ?of the exact location of the ground or material to be excavated, and, at the s'ametime, to positively feed said excavating material into a discharging trough or grunway, which maybe.

constructed to permit of wide lateral adjustment, to allow the excavator to cover a large ground area, as well as to enable the excavatetl material to be loaded into dump cars, eitherupon the same track as the car upon which the excavating machine is carried or into dump cars on either side thereof.

The invention further relates to the excavating mechanism; to the means for actuating the same; and, finally, consists in the features of construction and combination of claimed.

In the drawings, Figure-1 is-a side elevation of'said excavatlng machine in operative position; Fig. 2, a top or plan view thereof; Fig. 3, a top or plan view looking down upon the excavating machine when moved about on the car turn table; Fig. 4-,

parts hereinafter described and a side View of the carriage or car upon which the adjustable trough or runway is mounted; Fig. 5, a side view .of the frame 'carrying the excavating mechanism; Fig.

6, a detail showing a preferred form of trough or runway which is shown adjustably secured to the end frame; Fig. 7, a

sectional view taken through the excavating mechanism; and Fig. 8, a top or plan view of a portion of the excavating device.

This improved excavating machine is intended more especially for use in connection with railroad and construction work, and, as shown, said excavating machine is carried upon a fiat car 9 traveling upon the rails 10, said car having an engine 11 for actuating the turn table carrying the engine room 12 and for operating the excavating mechanism. 'An uprightsupporting frame 13 is fixedly positioned within the outer end 14; of the engine room and is connected by certain new and use upper actuating wheels or together. la r in construction and may be formed pref- I Specification of Letters.

any approved mechanism with the engine 11, and said supporting rame 13 engages a frame hearing at 15' to permit rotating frame movements back and forth as desired.

The excavating mechanism 16 is shown as traveling about oppositely disposed end actuating wheels or rollers 17 and 18. The rollers 17 are shown in Fig. as being spaced apart upon a shaft 19. communicating with any source of power for operating the same, said shaft 19 being secured to the opposite side frame rails 20'and 21 of the frame 13. Moreover, a sheave 22 is shown centrally keyed onto a transverse bar 23 rotatably secured within and to said frame rails 20 and 21 respecerate and engage with the oppositely disposed carrier wheels 27 which may be pivotally secured adjacent the respective side bucket frames 28 and 29 by transverse locking pins 30, of. any improved construction, which also secure the bucket frame sections The respective buckets are simierably of sheet metal having their respective end walls merge into elongated bucket bodies 31 which are each preferably provided with several projecting scraping blades or bars 32 which in Fig. 8 are shown secured to the bucket bottoms and have their inclined pointed edges 33 extending somewhat beyond the transverse bucket scraping edges 34.- As shown, the side bucketcarrier frames 28 and 29 each comprises a series of link members, for permitting the carrier frame to readily cooperate with the respective actuating wheels or rollers, and, as above indicated, the op posite ends of the link members carry the wheels or rollers 27 which are proportioned to register and seat withinthe respective notched peripheral openings 25 in the excavator actuating, wheels or rollers 17 and 18. the bucketsgjbeing locked to the links at their rear, as at 26, and in descending may assume substantially the position shown in Fig. 1. At the point where they contact the earth to be excavated their projecting scraper blades or bars 32 dig into the to extreme lateral position,

elongated trough orijrun vay' I j .v

laterally movable carr age ground, thus causing each bucket to filled as it ascends toward the point of dis-.' charge 36. -The earthy material, as it falls 4 mounted upon a y g or truck 40 having'its outeror discharging end 41 merging into an inclined discharge ing trough or chute 42 leading to 'a du'mp car 43, or otherwise. In Fig. 6 'i'sfshownja preferred form of 1I1te1l0r OOIiStIllCbliOIMOf said elongated chute or runway 38". 'which may comprise a which may-be formedl ,of; sheet metal of sufiicient strength otherwise as desired. In Fig? 4' is showna preferred form of said movable truck or carriage 40 traveling 'uponrails 46,- the car frame 47 carryin roller bearings. 48 upon which is 'mounte a truck frame 49'traveling about an axle or bearing post 50, said truck frame 49 having side bearings 51 and 52, in which an axle 53 is journaled and carries flanged wheels or rolle'rs 54 which normally contact the under side of the elongated conveyer chute or runway 38.

The excavating mechanism is rovided with a hoisting cable 55 secured at its lower end to the cross frame 56 adjacent the lower portion thereof, and said hoisting cable travels upon the sheave 22 and may travel at its lojver end about a winding drum, or otherwise actuated from any suitable source of power, for raising and lowering the excavating .mechanism carrying the traveling buckets.

In Figs. 1 and 2 the excavating machine is shown in position for excavating the gFround directly in front of it, whereas in ig. 3 the engine has moved the apparatus around such as would be assumed, for instance, in excavating ditches, and it will thus be noted that the elongated chute or runway 38 is readily capable of assumim said lateral position since it is adjustably secured to the upright frame 13, as well as to the laterally movable carriage 40. Moreover, the elongated trough or runway 38 is peculiarly mounted, since its combined adj ustmg means permit of lateral ircular, and lengthwise movement depen ing upon the position of the excavator.
